The new Fight Church documentary shows the two men engaged in the MMA craze that is taking the Christian world in the US by storm.
The trailer shows the two fighters hitting the floor as they endure simultaneous hits to the privates.
Fight Church explores the world of 'fight ministries', where pastors use combat as a tool to promote religious connection.
The film follows several pastors and popular fighters in a quest to reconcile their faith with a sport that many consider violent and barbaric.
Faith is tested and questions are raised as the makers of the documentary ask: can you really love your neighbour as yourself and then punch him in the face?
